Tattersall (2007) has cautioned that the Lepilemur species reported by Louis et al. (2006), all diagnosed exclusively on genetic distance and all allopatric, be treated with extreme caution until supporting data are forthcoming.

Justification:
The extent of occurrence (EOO) of this species covers less than 2,620 km2. This geographic range is severely fragmented and undergoing continuing decline in area, extent and quality of habitat. The number of mature individuals is also known to be in decline. Based on these premises, the species is listed as Endangered.

This species is found in northern Madagascar. Currently known from the Daraina region in northeastern Madagascar, south of the Loky River, with an additional population occurring in the Analamerana Forest. Sympatric with L. ankaranensis in the Andrafiamena Classified Forest. Field studies are needed to determine how these two species share the same forest. This is the only area where two Lepilemur species evidently occur in sympatry (Louis et al. 2006). The estimated extent of occurrence (EOO) is less than 2,620 km2.

Listed on CITES Appendix I. This species is known to occur in the Loky-Manambato Protected Area (Daraina), as well as in the Andrafiamena Classified Forest, which is slated to become a national park. Further work is now urgently needed to clarify the distribution and taxonomic limits of the recently described Lepilemur species.
